Application filedApril 30, 1925. SerialNo. 210,82.

The present inventionl relates to improvements to fastening devices for Windows. In

carrying out my invention I propose'to pro* vide-a simple and efiective fastener comprisf ing two elements which -fmay be attached to.

the meeting rails of the window, and which will automatically engage each other to faslten Vboth* of Vthe sashes. VI also propose to provide a device, whichmay be readily attachedto the ineeting rails of' the upper and 'lower sashes, and adapted to .automatically move into looking position When the sashes vare closed upon the frame. It is a still further object of my invention tov provide' means for automatically latching two sashes when the 'same are closed, which shall ein-y body the desirable features of simplicity in vice automatically*v secures the sashes closed, but not'latched or Secured. My de,-

get-her when the sashes are closed.

v Referring to the drawings:

.v sh'owingthe two heads in latched position.

Fig. 2. Is a perspectiveview of my inventionV showing the latched position on the meeting rails of the sashes.

-Myinvention consists of twofmetal pia-tes 'having heads bent vin the form of an acutev angle, each fittng exactly into the, other,

; and having /at their operative extremities short right angled port-ions bent inwardly p i outei' headbeingprovifdedflwith aii opening 'large enough to allow thedepressioii of theV to 'form Va latchng means.V rllhc inner plate [is/of spring'metal.
